The actual harsh truth about MAHA is that it is an anti-vaxx, anti-science, pro-diarrhea conspiracy movement.

I appreciated this thoughtful commentary on our recent (surprisingly "negative") study of private equity's effect on cancer care. I would summarize as: we looked only at one form of harm, and other potential harms have not been excluded. academic.oup.com/jnci/advance...

Private equity acquisitions and cancer care: nothing to see here? Not so fast.
